Trees felled by Haiyan used to build homes

Millions of trees felled or damaged during Typhoon Haiyan will be milled and used to rebuild homes in devastated areas of the Philippines, says an Australian relief worker.

Haiyan killed more than 6100 people and left around 1800 missing when it tore through the central Philippines last November.

The typhoon, one of the deadliest natural disasters in Philippine history, also knocked over more than 16 million coconut palm trees.

Australian Red Cross worker Chris Howe is co-ordinating a program to use some of the felled trees in the massive rebuilding task.

He says timber could be harvested from around eight million trees, creating a huge resource for coconut farmers who had seen their crops wiped out.

"Instead of giving money away, the relief agencies are investing money and then getting a return in the form of the timber," he told AAP on Thursday.

Mr Howe said trees that are not big enough to be milled could be mulched or chipped for local farmers.
